DETAILED DESCRIPTION

More detailed description of the preferred embodiment of the poweredgolf bag vehicle with speed control will be given below with referenceto the drawings.

Now, referring to FIGS. 1, 5 and 6, the powered golf bag vehicle withspeed control according to the present invention includes a driveportion comprising a battery case 7, a built-in motor 907, a drive wheeland its accessories, a speed control portion comprising a speedregulator 10, an optical counter 1007, a PC circuit board and itsaccessories, a main body portion comprising a frame 1, a golf bagsupporter 2, a golf bag holder 3, a battery case 7 and its accessories,a foldable portion comprising a foldable handle with latching device 4,a foldable support with connecting rod 5 and its accessories, atraveling portion comprising a drive wheel, a wheel 6, a wheel axle 905and its accessories, wherein the traveling portion and the foldableportion carrying the main body portion accomplish a traveling movementof the vehicle through the driving force of the drive wheel with movingspeed preset and controlled by the speed control portion.

Now referring to FIGS. 2 through 5, the drive wheel according thepresent invention comprises a tire 901, a boss 902, a friction ring 903coupled to the boss, an axle bearing 904, a wheel axle 905, a motor 907and a bracket for the motor 906 (as shown in FIG. 5); the assemblycomprising the above parts is enclosed in a space formed by the foldedtire and the boss (as shown in FIG. 4). A rolling friction face 9031 isformed on the friction ring 903 along the inner circumference thereof(as shown in FIG. 6). The motor 907 is provided with a output axis 9071reaching out at the two ends thereof and the motor 907 is coupled to thebracket for the motor 906 that is coupled to the wheel axle 905connecting to the boss 902 through the rolling bearing 904 (as shown inFIG. 6). An optical counter 1007 is provided on one end of the outputaxis 9071 of the motor. (as shown in FIG. 6).

After the motor is powered on, the motor will rotate and the output axis9071 will have rolling friction with a friction face 9031 of thefriction ring 903 and thus making the boss rotate. Two motorsrespectively driving a left boss and a right boss are controlled by thecontrol portion so that they operate synchronously. At the same time,the optical counter 1007 provided on one end of the output axis 9071rotates with the motor so as to measure the rotate speed of the motor.

Now referring to FIGS. 7 and 8, the traveling speed of the presentinvention is predetermined and controlled by the PC control system tokeep the traveling speed as predetermined under different operatingconditions, for example, ascending, descending or uneven surface. Thespeed control system comprises the speed regulator 10, the opticalcounter 1007 provided on the output axis 9071 of the motor, and a PCcircuit board enclosed in the case for PC circuit board.

Now referring to FIG. 9, the resistance value of a variable resistor forspeed control 1006 in order to regulating the traveling speed isadjusted by turning a regulating knob 1004 provided on the speedregulator 10. The voltage value set by the variable resistor for speedcontrol 1006 is transmitted to a central process unit (CPU) via a D/Ainterface and output to a drive interface by way of PWM to rotate themotor. The rotate speed of the motor can be changed by altering thebandwidth without changing the output voltage. When the traveling speedchanges, the optical counter 1007 transmits a signal to CPU via the A/Dinterface. The signal is then processed by the CPU and output to thedrive interface via the D/A interface by way of PMN, such that theoutput power is automatically changed according the changes of the load.For example, the output power will increase when traveling on anascending surface and decrease when traveling on a descending surface tomaintain the predetermined the traveling speed. At the same time, a theload of the motor is monitored by a overload circuit monitor, and thebattery voltage is detected by a battery voltage detecting interface inorder to avoid overload and overcharge of the battery by display thebattery voltage status by a indicator via an I/O interface.

Now referring to FIG. 2, in the powered golf bag vehicle with speedcontrol according to the present invention, wheels 6 and a drive wheel 9forms a tripod structure (as shown in FIG. 1) through a foldable handlewith latching device 4, a foldable support with connecting rod 5, and aframe 1; and a main body for carrying objects (as shown in FIG. 3) isformed by, and a golf bag supporter 2, a golf bag holder 3, a batterycase 7, and a frame 1.
